What is a programmable room thermostat?... an explanation for householdersA programmable room thermostat is both a programmer and a room thermostat. A programmer allows you to set ‘On’ and ‘Off ’ time periods to suit your own lifestyle. A room thermostat works by sensing the air temperature, switching on the heating when the air temperature falls below the thermostat setting, and switching it off once this set temperature has been reached.So, a programmable room thermostat lets you choose what times you want the heating to be on, and what temperature it should reach while it is on. It will allow you to select diff erent temperatures in your home at diff erent times of the day (and days of the week) to meet your particular needs.Turning a programmable room thermostat to a higher setting will not make the room heat up any faster. How quickly the room heats up depends on the design of the heating system, for example, the size of boiler and radiators.Neither does the setting aff ect how quickly the room cools down. Turning a programmable room thermostat to a lower setting will result in the room being controlled at a lower temperature, and saves energy.The way to set and use your programmable room thermostat is to fi nd the lowest temperature settings that you are comfortable with at the diff erent times you have chosen, and then leave it alone to do its job. The best way to do this is to set low temperatures fi rst, say 18°C, and then turn them up by one degree each day until you are comfortable with the temperatures. You won’t have to adjust the thermostat further. Any adjustments above these settings will waste energy and cost you more money.If your heating system is a boiler with radiators, there will usually be only one programmable room thermostat to control the whole house. But you can have diff erent temperatures in individual rooms by installing thermostatic radiator valves (TRVs) on individual radiators. If you don’t have TRVs, you should choose a temperature that is reasonable for the whole house. If you do have TRVs, you can choose a slightly higher setting to make sure that even the coldest room is comfortable, then prevent any overheating in other rooms by adjusting the TRVs.The time on the programmer must be correct. Some types have to be adjusted in spring and autumn at the changes between Greenwich Mean Time and British Summer Time.You may be able to temporarily adjust the heating programme, for example, ‘Override’, ‘Advance’ or ‘Boost’. These are explained in the manufacturer’s instructions.Programmable room thermostats need a free fl ow of air to sense the temperature, so they must not be covered by curtains or blocked by furniture. Nearby electric fi res, televisions, wall or table lamps may prevent the thermostat from working properly.

An introduction to your programmable room thermostat

Your programmable room thermostat allows you to programme diff erent temperatures at diff erent time periods. You can programme one set of times and temperatures for week days with a diff erent set of temperatures for weekend days, this is referred to as 5/2 day operation.

The thermostat can also be set up by your installer to provide one set of times and temperatures that are repeated each day of the week. This is referred to as 24 hour operation.

The thermostat can also be set by you to provide two diff erent programming blocks which can then be assigned to any day of the week, this is referred to as A/B programme operation.

All thermostats can be set by your installer to provide up 2, 4 or 6 time and temperature settings each day.

All thermostats feature useful overrides, including a programmable frost setting.

Your thermostat has some advanced features which the installer will set-up if they are required. There are also a number of advanced features which can be set up by you. These advanced settings alter the way that your thermostat operates, some also aff ect the programming functions and the user overrides. Please read the User Advanced Programming instructions before programming the unit (see page 25).

Preset programmes

Your TP5000 Si comes ready programmed with a set of operating times and temperatures which suit most people. Please remember that some of the options available will depend on how the installer has set up the unit.

Note: If set up for 4 events per day, events 3 & 4 are skipped. If set up for 2 events per day, events 2, 3, 4 & 5 are skipped. In both cases the events are re-numbered.

Before you start

Open the fl ap on the front of the programmer and press the RESET button with a non-metallic object until the display goes blank. This will ensure that the micro-computer in the product is operating correctly.

Customising the display

For the sake of clarity, the instructions assume that the display setting uses a 24 hour clock, °C and that days of the week are shown as text. All of these settings can be personalised after the thermostat has been programmed, see pages 22 - 24.

Setting the correct date and time

Your TP5000 Si incorporates a real time clock with calendar function that automatically changes time in both Spring and Autumn. The time and date is set in the factory for the UK time zone, and does not normally require adjustment. If you live in another time zone refer to “Time zone off set” on page 26. However, should it be found necessary to adjust time or date for any other reason refer to the following instructions.

Option 11 - Start-up methodYour thermostat can start up the system in three diff erent ways. Press + until Option 11 is displayed, use Λ and V to select required setting.Setting 0 Normal: Heating is turned up or down at the programmed

times.Setting 1 Optimum start control (OSC) (or Comfort Setting): This

allows you to programme the time at which you would like to be up to the required temperature. The thermostat then calculates how soon before the required time the heating is turned up. This will vary with weather conditions ranging from a maximum of 120 minutes to 0 minutes before the programmed event time. This setting must be used together with option 12 to match the optimiser setting to the building in which it is installed.

Setting 2 Delay start (or Economy Setting): This is an alternative to OSC. Set the event times in the normal way taking into account the time that the building takes to heat on an average day. The thermostat monitors switch on time, actual temperature and wanted temperature and delays the start of the heating if the actual temperature is close to the programmed temperature.

Option 13 - Optimum start control/Delayed start event setting(Option 11 set to 1 or 2)The Optimum start or delayed start control can be applied to event 1 only or to each event of the day which requires a higher temperature than the previous event. Press + until Option 13 is displayed, use Λ and V to select required setting (only active if Option 11 is set to 1 or 2).Setting 0 Applies only to fi rst event of day. (Factory setting)Setting 1 Applies to each event of the day that requires a higher

temperature compared to previous event.

Option 12 - Optimum start control pre-heat setting (Option 11 set to 1)Press + until Option 12 is displayed, use Λ and V to select required setting (only active if Option 11 is set to 1).The optimum start control must be adjusted to match the building energy characteristics. Use the Λ and V keys to selected the required pre-heat period. The table below suggests typical settings.If the building fails to reach temperature on time, increase the setting by 15 minute steps each day until the correct setting is found.If the building reaches temperature ahead of time, decrease the setting by 15 minute steps each day until the correct setting is found.0:15 15 mins, warm air systems, well insulated building.0:30 30 mins, warm air systems, well insulated building.0:45 45 mins, warm air system poorly insulated building.1:00 60 mins, radiator system, light weight well insulated building.

Overview of installer selectable features which may aff ect the operation of your thermostat

Temperature range limitation

This allows the installer to programme both upper and lower temperature limits. It may limit the upper and lower temperature that you are able to set on the thermostat.

Temperature override limitation

This allows the installer to limit the number of degrees that you can override the programmed temperature by, it also allows the installer to set rules regarding how long a temperature override will remain in place.

Keyboard lock

This allows the installer to limit or lock the keyboard to prevent unauthorised changes to programme values and limits overrides.

What happens to the unit when batteries fail

If batteries are not changed within 15 days of a low battery warning, the unit shuts down. In normal circumstances the thermostat turns off the valve or the boiler it is controlling. In extreme climates turning off the heating is likely to result in the building freezing up. To prevent this, the installer can set up the unit to turn the heating ON rather than turn OFF on battery failure. This will consume more fuel but will prevent damage occurring to the building. If appropriate please check that the installer has set this function correctly.

Please note: If you replace the batteries and the LCD does not come on immediately please check battery orientation. Do not leave batteries in the product if the display is not active.

If, after changing the batteries, the screen remains blank it is necessary to carry out a partial reset. See page 30 for details.

Resetting the unit

Partial reset: Press RESET (used to restart micro-computer) if display freezes for any reason. This does not reset any programme, clock or date. It is recommended that this is done at time of installation.User full reset: Press RESET whilst holding down PROG button. This resets event times and any User Advanced Programme setting, but does not reset time or date.Installer full reset: This is only available to the installer. In addition to the above all of the Installer Advanced Programming settings are returned to factory settings, however, time, date and service due date are not reset.

Service Interval Timer

If the property is owned by a landlord he may, for gas safety reasons, have instructed the installer to set the service interval timer. If set, 28 days prior to the service due date, a visual and audible warning will start each day at noon. The audible warning will last for 10 seconds and will be repeated every hour until a button is pressed to cancel it. If cancelled the alarm will recommence the following day at noon. If the boiler is not serviced before the due date, a visual and audible warning will start each day at noon. The audible warning will last for 1 minute and will be repeated every hour until a button is pressed to cancel it. If cancelled the alarm will recommence the following day at noon. In addition, all overrides and programming buttons will be disabled and the heating may operate for a limited amount of time each hour. The installer may cancel or reset the service interval timer as part of the boiler service. This is a gas safety feature that can only be accessed by an installer.
